① Microwave-safe with lid Set of 5 -20℃ to 140℃ compatible Polypropylene 10.9cm x 7.9cm x 4.5cm height 220ml I used one, so there are 5 remaining. These have been stored at home for a long time. ② Kureha, one serving of rice, can be frozen and stored, and the lid can be microwaved. It's a light and durable container. Set of 2 -20℃ to 140℃ compatible Polypropylene 250ml I stored these in the original box in the cupboard, but the box is dirty. These have also been stored for a long time. When shipping, I will take the set of 5 out of the bag and put them in a new bag, and I will pack the instruction part together. If you don't mind the above, please consider purchasing.
